The rise of climbing: how a niche sport went mainstream

From the fringe to the feed

Not long ago, telling someone you went climbing meant explaining yourself. Were you on a mountain? With ropes? Is that not dangerous? Today most people have a friend who climbs, a gym down the road, or a memory of watching it at the Olympics. Climbing has quietly become one of the fastest-growing ways to move, and the shift has happened in barely a decade.

The headline moment was the Games. Sport climbing made its Olympic debut at Tokyo 2020 (held in 2021), and the timing was extraordinary — a sport that thrives indoors arriving just as the world was rediscovering exercise close to home. By Paris 2024 it had grown from two medal events to four, with the athlete field expanding from 40 in Tokyo to 68. At Los Angeles 2028, the three disciplines — bouldering, lead and speed — will each become their own medal event. A sport that once lived in quarries and converted warehouses now has a permanent seat at the biggest table in sport.

Why it caught on

The Olympics threw fuel on a fire that was already lit. Climbing was growing before Tokyo, and there are good reasons it kept going:

• It does not feel like exercise. Every climb is a puzzle. You are so busy working out the moves that the workout sneaks up on you.
• It is social by default. You belay, you spot, you trade beta. A bouldering wall is one of the easiest places to fall into conversation with a stranger.
• The barrier to entry is low. Hire some shoes, chalk up, and you can have a brilliant first session with zero technique. Few sports give beginners that much fun on day one.
• It scales with you. The same wall holds a problem for your first week and a problem you will still be failing on next year.

That combination — playful, sociable, accessible, endlessly deep — is rare, and it travels well from city to city.

The gym boom

The clearest evidence is bricks and mortar. According to the Climbing Business Journal, which tracks the industry, North America passed 870 commercial climbing gyms in 2024, having added new ones every year for well over a decade. Most of that growth has come from bouldering-focused gyms — no ropes, no belay courses, just pads, problems and a social floor. Market analysts now value the global climbing gym market in the billions and expect it to keep growing at close to ten per cent a year.

New gyms bring new climbers, who bring their friends, who eventually try real rock. The indoor boom has fed the outdoor scene rather than replacing it.

What it means for you

A bigger sport is a better sport to be part of. There are more gyms within reach, more partners to climb with, more coaching, and far more beginner-friendly culture than the sport had twenty years ago. It also means busier walls, fuller car parks at popular crags, and a real responsibility to look after access and the places we climb.

For most of us, though, the boom is simply good news. Climbing is easier to start, easier to keep up, and easier to share than it has ever been. The mainstream finally caught up with what climbers always knew — that there are few better ways to spend an afternoon than figuring out how to get to the top.
